Received power for Reconfigurable Intelligent Surface use case

Received power in the sampled analyzed area (shown in file area.png) in a scenario with single room with a short wall, and signal transmitter behind this wall. Output was generated with usage of the MATLAB raytracing tool. 

Analyzed area was sampled in both dimensions, creating 99 points in x-axis (values between 3 meters to 7.9 meters with 5 cm step), and 89 points in y-axis (values between 2.2 meters to 6.6 meters with 5 cm step). Reconfigurable Intelligent Surface was placed with 9 configurations of angle (angle between RIS surface and wall) from -20 to 20 degrees with 5 degree step. This setup created 9 files (for each angle) and inside file there is received power for each analyzed area point (99x89).
